Laravel 4遷移 - 類未找到

Question

這個問題現在已經解決了 - 我用下面的：

而且，問題就解決了由於IRC。我被告知要運行

php composer.phar dump-autoload 

這解決了我的問題。這可能與我奇怪的Composer設置有關。

php artisan migrate:make create_blogs_table --table=blogs --create 

此：

我剛開始用Laravel 4打了一個可能的未來的項目中，已經進入從Laravel 3.我已經通過創建一個新的遷移，create_blogs_table使用工匠開始了生成的基本遷移的文件結構，然後我填寫了一點：

<?php 

use Illuminate\Database\Migrations\Migration; 

class CreateBlogsTable extends Migration 
{ 

    /** 
    * Run the migrations. 
    * 
    * @return void 
    */ 
    public function up() 
    { 
     Schema::create('blogs', function($table) 
     { 
      $table->increments('id'); 
      $table->string('title'); 
      $table->text('description')->nullable(); 
      $table->integer('user_id')->unsigned(); 
      $table->timestamps(); 
     }); 
    } 

    /** 
    * Reverse the migrations. 
    * 
    * @return void 
    */ 
    public function down() 
    { 
     Schema::drop('blogs'); 
    } 
} 

我現在嘗試再次使用人員能夠運行這個遷移：

php artisan migrate --env=local 

*注意我有一個本地數據庫連接設置爲與.dev擴展域

以前，這會工作得很好（在Laravel 3），但照亮我再收到此錯誤：

我檢查過，數據庫/ migrations /文件夾肯定是自動加載的。我不知道這個問題的原因可能是什麼。詢問了IRC並使用Google搜索後，我仍然完全無能爲力，希望有人能幫助我。

在此先感謝！

Answer 1

在Laravel 4（照亮）遷移類中不需要您設置未簽名的方法。你可以試試這個。

class CreateBlogsTable extends Migration 
{ 

    /** 
    * Run the migrations. 
    * 
    * @return void 
    */ 
    public function up() 
    { 
     Schema::create('blogs', function($table) 
     { 
      $table->increments('id'); 
      $table->string('title'); 
      $table->text('description')->nullable(); 
      $table->integer('user_id'); 
      $table->timestamps(); 
     }); 
    } 

    /** 
    * Reverse the migrations. 
    * 
    * @return void 
    */ 
    public function down() 
    { 
     Schema::drop('blogs'); 
    } 
} 

跟你聊天后，我知道兩個問題，一個是上面已經提到，另一個問題是由於沒有被註冊到作曲家自動加載的類。你將不得不手動運行：PHP composer.phar轉儲自動加載

Answer 2

我對Xubuntu的這個錯誤，使用sudo作曲家轉儲自動加載固定它

Answer 3

工匠做同樣的工作：

php artisan dump-autoload 

只是提醒那些不熟悉composer的人。

Answer 4

更新您的作曲家（composer self-update），然後運行您的作曲家功能。
